This document establishes minimum performance criteria at GCWR and calculation methodology to determine tow-vehicle TWR for passenger cars@ multipurpose passenger vehicles and trucks. This includes all vehicles up to 14000 lb GVWR. Purpose This document establishes tow-vehicle performance requirements for combination vehicle acceleration@ gradeability@ understeer@ trailer sway response@ braking and park brake at GCWR@ and tow-vehicle hitch/attachment structure at TWR. In order to minimize test variations@ it provides standard test trailer specifications and requirements for use in these tests. It is acknowledged that there are a wide variety of conditions experienced while trailering which cannot be completely addressed within this document and in no way is this document intended to establish or limit manufacturers' designs or instructions to the customer. This document provides equations to determine TWR from GCWR in conjunction with other vehicle ratings and defined vehicle weight conditions and dimensions. Vehicles rated under this document are subject to normal production variation and it is intended that most vehicles of a specific model that is marketed as meeting SAE Recommended Practice J2807 shall meet the performance requirements in this standard. As a secondary purpose@ this document may be used as a benchmark to qualify the performance of a specific trailer design. Thetow vehicle and trailer setup criteria should follow the trailer manufacturers' specifications when used for this purposeand may differ from the setup criteria required by the sections below.
